Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Red potatoes
- Their starchy interior turns soft and fluffy while the cut surfaces crisp and brown.
- Olive oil
- Fat conducts heat evenly and helps the potato surfaces brown and crisp.
- Onion
- Softens and caramelises in the oven, adding sweetness and savoury depth.
- Garlic
- Releases aromatic compounds as it cooks, adding a pungent, savoury flavour.
The step that matters
Toss with remaining ingredients. Coating the potato pieces evenly in oil and seasoning lets every surface brown and season consistently. Dry, well-scrubbed pieces brown better than wet ones, so they should be patted dry before tossing.
Swap the clove
How well each one fits the dish's main ingredients (potato, olive, parsley, onion, garlic, pepper):
- Thymefits better
- Cuminfits better
- Rosemaryfits better
- Clovethe original
Fit is the average pairing score against potato, olive, parsley, onion, garlic, pepper. Candidates are from the same food group and used in at least 100 recipes.
